For an XC freehub, either mono,sport,ti-glide will fit. Bulb and big un are wider and dont fit.
There is honestly not a lot can go wrong with them. Any play would usually be down to bearings or even a bent axle. There should also be a spacer sits in the inside recess between the back of the freehub and the main bearing in the hub- Check to see that is there.
I’ve checked my box and only got a couple of slightly damaged bulb freehubs sorry to say, as above with S/King i sold pretty much all the saleable hope bits to pay for the ebike.
I also see your wanted ad was posted Feb, so maybe give it a bump. RB’s a bit quiet these days and not everyone comes in daily.
In all honesty I would look to see if its something other than the freehub itself. As said, not a lot can wear with them,and there is a very slight wobble normally, and I couldnt say they are as play free as todays Hope freehubs.
